Amazon Fargate Quick Start Guide

By: Deepak Vohra

Overview of this book

Amazon Fargate is new launch type for the Amazon Elastic Container Service (ECS). ECS is an AWS service for Docker container orchestration. Docker is the de facto containerization framework and has revolutionized packaging and deployment of software. The introduction of Fargate has made the ECS platform serverless. The book takes you through how Amazon Fargate runs ECS services composed of tasks and Docker containers and exposes the containers to the user. Fargate has simplified the ECS platform. We will learn how Fargate creates an Elastic Network Interface (ENI) for each task and how auto scaling can be enabled for ECS tasks. You will also learn about using an IAM policy to download Docker images and send logs to CloudWatch. Finally, by the end of this book, you will have learned about how to use ECS CLI to create an ECS cluster and deploy tasks with Docker Compose.

Chapter 3. Using CloudWatch Logs

Docker containers generate logs, and Docker supports the docker logs and docker service logs commands to list logs. Docker also supports logging drivers, which are logging mechanisms to get logs generated by running containers and services.

Problem: Without a managed service, such as Amazon ECS, a logging driver must be configured if a logging mechanism is to be added.

Solution: With the Fargate launch type, logging is greatly simplified and the only supported logging driver is awslogs. The awslogs logging driver streams logs generated by ECS tasks to CloudWatch Logs. Using aws-logs-prefix, a label may be associated with the awslogs driver to differentiate between the log streams generated by the different tasks containers.

In this chapter, we will learn about the following:

  • Overview of CloudWatch Logs and aws log driver
  • Creating an ECS service for a MySQL database
  • Configuring a Container definition
  • Configuring logging
  • Configuring a Task definition
  • Configuring a service...
